the application of Multiband in CFX
 

The multiband spectral model in CFX discretizes the spectrum into bands of finite width and assumes that the radiation quantities are nearly uniform within the band. But from the help document, It means that the multiband assumes thant the emissivity of the every band is 1.

In my opinion, the emissivity of the every band should be decided by the user. But I can not find the place to input the emissivity.


Does anyone have this problem and can give me some advise.

Thanks~!
